The documentation of Visual Studio 2013 stated:
"Visual Studio add-ins are deprecated in Visual Studio 2013. You should upgrade your add-ins to VSPackage extensions."
And in the next version Visual Studio "14" add-ins will be removed (the "Add-In Manager" menu item no longer exists). So, it is time to convert add-ins to packages.
